I am re-using a set of slides and I want to get rid of a corporate logo that is sitting on the lower left corner of the slides. I don't want to hide background graphics, I want to get rid of the image from all the slides.

I don't know if it's part of the background, footer, or some other part of the design. I've tried working in View/Slide Master but cannot get to a place where I can remove the logo. It's apparently not part of the footer, because going into the edit footer option doesn't work.

Any help will be appreciated. Thanks in advance.
